Paper of the Month: Long-term antithrombotic therapy and risk of intracranial haemorrhage from cerebral cavernous malformations: a population-based cohort study, systematic review, and meta-analysis
This month’s selected paper addresses the risk of neurological deficits in people with cavernomas treated with antithrombotic medication. Perhaps counter-intuitively, the authors report a lower risk of intracerebral haemorrhage in patients taking antithrombotic medication (mostly antiplatelet therapy). The study therefore provides reassurance for clinicians managing patients with this relatively common, and often incidental, vascular finding that antithrombotic therapy does not appear harmful; conversely, there could be some benefit, but this requires further evaluation in a randomised controlled trial.
